OUTSTANDING TOOL OF THE CONCRETE CONSTRUCTION INDUSTRY! 




UMPCRETE, America's only concrete pump, has come of age! 
Rapidly since its introduction in 1932 — and at an accelerated 
pace during the past few years — the cost-cutting abilities of the 
Rex Pumpcrete and its pipe line have become identified with more 
and more concrete structures of all sizes and all classifications, 
men throughout the construction industry, Pumpcrete has become a 
standard tool, to be used consistently on job after job; to be looked 
upon as a factor which means savings in cost and time and which 
will permit speeding up all other operations on the job with a con- 
sequent reduction in overhead. 



The Reasons 



This Success 



The reasons for Pumpcrete's remarkable record of pumping millions 
of yards of concrete in a few years are simple. Pumpcrete takes con- 
crete placing out of the "lift-and-carry" category and makes it a 
simple pump and pipe-line proposition. 

It saves time and money formerly spent in erecting and operating 
buggy-runs, chutes, hoists, towers, and other old-fashioned equipment. 

It simplifies difficult jobs. 

It permits a more orderly, economical job progress. 

It is a direct link between mixing unit and forms — often eliminating 
rehandling equipment. 

It does all this — and it does it consistently on jobs ranging in type 
and size from the Navy's largest dry docks to the simplest culvert or 
foundation.

Here's How Simple the Pumpcrete is! 



A remixing hopper, two valves, a piston and a cylinder! 
crete! It's as simple as the piston-type water pump 
Replaceable liners protect all wearing parts! 



That, basically, is all there is to the Rex Pump- 
- as easy to operate as your concrete mixer!

Every once in a while there appears a machine that 
"clicks" right from the start— that moves into the aver- 
age contracting setup and starts performing mechani- 
cally and from the cost and profit standpoint in a way 
that immediately shows its superiority over machines 
and methods previously used. 



That's the case of the Rex Pumpcrete. While this con- 
crete pump is not the answer to every concrete plac- 
ing problem, it offers so many fundamental advantages 
for such a wide variety of concrete construction work 
that it has been accepted as a standard tool of the 
industry — a low-cost method of placing concrete on 
concrete jobs all over the country.

3-WAY SELECTIVE DRIVE FOR DOUBLE PUMPCRETES! 




Rex Double Pumpcretes operate on the same principles as the 
Single Pumpcrete described above, except that they have two 
pumping cylinders instead of one. They are equipped with the 
Rex 3-Way Selective Drive transmission which enables the opera- 
tor to pump through both cylinders simultaneously to gain full 
pumping capacity or to shut down either side of the pump without 
interfering with the continuous flow of concrete from the other 
cylinder. Because of this, the 3-Way Selective Drive effectively 
answers the requirement of standby equipment contained in the 
specifications on many important jobs. On pours where two points 
are being placed simultaneously, the 3-Way Selective Drive 
enables the operator to slow up the flow of concrete in either pipe 
line to regulate the rate of pour — this is often a necessary process, 
as on the overbreak in tunnels. On other types of jobs where two 
mixes are used, the selective drive enables them to be pumped 
through separate pipe lines at the same time, merely by using a 
simple partition in the hopper. You get three Pumpcretes in one 
with this new 1941 Pumpcrete feature! 



This drawing shows how the 3-Way Selective Drive 

gives you three Pumpcretes in one.

IT'S 



EASY 



TO 



SET 



UP 



THE 



PIPE LINE ! 



Not the least of Pumpcrete's many unique features is its easily handled 
pipe line! Pipe line comes in a variety of convenient lengths shown 
on page 23) which enable you to reach any point on the job from the 
Pumpcrete setup— and to have enough additional pipe ior the most 
economical job progress. Once your Pumpcrete is spotted, pipe line 
is laid from Pumpcrete to final delivery point and pipe sections are 
qu ly coupled or uncoupled with the simple "toggle" couplings 



PIPE CLEANING'S 



illustrated above. No bolts or wrenches are required. Coupling or 
uncoupling the Rex pipe line requires but a few seconds for each 
connection, and you can uncouple the pipe without interfering with 
the flow of concrete. The Rex toggle coupling is positive and fool- 
proof and gives the connected pipe line the required rigidity without 
further lateral bracing.

HOW TO FIGURE 



PIPE 



LINE FOR YOUR JOB... 



The following table of Pipeline Data is based on con- 
verting the pumping resistance of any combination of 
straight pipe, bends and differences in elevation to the 
resistance of an equivalent length of straight horizontal 
pipe: 

Equivalent 

Length of Maximum 

Straight Aggregate 

Horizontal Vertical Square 

Pipe Size Pipe* Distance** Screen Size

7" 1000 ft. 100 ft. 2" 

WITH REX PUMPCRETE No. 160 (6.3") 
6" 800 ft. 100 ft. 2" 



♦A 90 degree bend is figured as equivalent to 40 ft. of horizontal piping, 
a 45 degree bend equivalent to 20 ft., and 221'2 degree bend equivalent 
to 10 ft 

**Not over 200 ft. of pipe actually. A combination of horizontal and ver- 
tical distances is to be calculated on the basis of I ft. of vertical equal- 
ing 8 ft. of horizontal pumping. The total equivalent distance should 
not exceed the equivalent horizontal pumping distances shown in the 
tabulation. 



Example: 

Assume the project is equipped with a single Pump- 
crete, Model No. 200, pumping through 8" O. D. pipe- 
line. 

The total actual length of pipe line is 360 feet, which is 
made up of the following sections: 

320 ft. straight pipe 
2—90- bends 
4—45 bends 

There is a vertical lift at the end of the pipe line of 40 ft. 

The equivalent length of straight horizontal pipe is 
determined as follows: 

320 ft. straight pipe Equals 320 ft. 

2—90 bends (Equivalent to 40 ft. straight 

pipe) 80 ft. 

4 — 45 bends (Equivalent to 20 ft. straight 

pipe) 80 ft. 

40 ft. vertical lift (Equivalent 1 ft. vertical 

equals 8 ft. horizontal) 320 ft. 

800 ft. 




The following straight line curves are pre- 
sented so the contractor may better judge the 
amount of concrete in the pipe line. The in- 
formation is of great value in holding con- 
crete losses to a minimum when nearing 
the end of a pour. 

The quantity of water required to clean out 
the pipe line with the Go-Devil may be com- 
puted from the above table by converting 
cubic yards of concrete into gallons of water. 
(1 cubic yard equals 202 Vi gallons.)

IF YOU BID BUILDINGS, WAREHOUSES, FACTORIES, STEEL MILLS 

HOUSING PROIECTS, ETC. 




The picture at the left shows the pipe 
line set-up for pouring 5.000 yards of 
concrete in the roof and floor construc- 
tion (an area of 225,000 sq. ft.) on the 
Brooklyn High School for Homemaking. 
Concrete for dozens of other buildings, 
warehouses, steel mills, plants large 
and small, containing anywhere from 
1,000 to more than 100,000 yards, has 
been pumped in place by the Pump- 
crete. Doesn't this show adaptability and 
wide range usefulness? You'll know 
how true this is when you figure plac- 
ing costs in your building work. Com- 
pare Pumpcrete costs against those of 
any other placing method. The chances 
are 10 to 1 that you'll find you can do 
it cheaper with the Rex Pumpcrete. 

These are facts -facts you should con- 
sider when deciding on your concrete 
placing methods.

100 ft. above the Pumpcrete), elimina 
ing towers, hoists, buggies, and other 
costly placing units. 



10 



















As a unit for transporting and placing 
concrete in tunnels the Rex Pumpcrete 
has a performance record that no other 
method can approach for fast, efficient, 
low-cost placement of high quality con- 
crete. Pumpcretes have placed millions 
of yards of concrete in the rock tunnels 
of the famous Colorado River Aqueduc*; 
in the muck tunnels of Chicago and 
Detroit; in the treacherous ground under 
New York City and many other local- 
ities. Pumpcrete's background includes 
dozens of other tunnel jobs ranging 
from the world's largest tunnel, the 
Yerba Buena Tunnel in San Francisco 
down to a 4 l 2 foot tunnel in Gary. At 
the right is a photo of the Rex 200 
Single Pumpcrete placing concrete in 
the new Chicago Subway. This all- 
around ability on all types of tunnel 
jobs means something to you if you are 
after tunnel contracts — it means that 
Rex Pumpcrete is a tried, proved method 
of cutting your placement costs on your 
jobs!

The Rex Pumpcrete has shown remark- 
able success in placing concrete for 
structures in this class of work — from 
the large jobs over 10,000 yards down 
to the small 500 yard overpass or under- 
pass. The photo at the left shows the 
set-up used for the 10,000 yard West

Pumpcretes have cut placing costs on 
dozens of lock and dam jobs! This in 
eludes over 14 Mississippi River lock 
and dam jobs where Pumpcretes pump 
ed and placed over a million cubic 
yards! Pumpcretes placed approxi 
mately 275,000 cu. yds. of concrete in 
the world famous Boulder Dam! Pump 
cretes have placed hundreds of thou 
sands of yards of concrete on all sizes 1 
and types of hydro-electric dams, spill 
ways, earthen dams, flood control pro 
jects, etc., from Bonneville, Oregon, tc 
Seboomook, Maine. The Rex 160 Pump 
crete with its capacity of 15 to 20 cu 
yds. per hour has set an enviable 
record on smaller jobs of this kind 
Such a background of successful per 
formance is ample evidence that Pump 
crete is thoroughly adaptable to this 
class of work — evidence that yoi 
should bid with this advantage rathei 
than against it! 



BID SEWAGE AND WATER TREATMENT PLANTS OR RESERVOIRS 



ige s, filtration plants and 

with combinations of slabs, 
am and columns placed over 
ipaiatively wide area are ideal 
npciete jobs. Rex Pumpcretes have 
laced concrete on this type of work in 
practically all parts of the U. S. A. This 
includes job6 as small as a 1.500 yard 
sewage treatment plant at Two Rivers, 
Wisconsin, 50,000 yard jobs in Milwau- 
kee and Detroit, and the 200.000 yard 
ago Filtration Plant. Shown here is 
the Jamaica, Long Island, New York 
Sewage Disposal Plant in which a dou- 
ble Pumpcrete placed 35.000 cubic 
yards into circular tanks of 80 and 120 
foot diameters. The pipeline set-up was 
made for continuous pouring at a rate 
of 50 cubic yards per hour.

YOU 



MARINE WORK 






Marine work of all kinds including 
causeways, breakwaters, jetties, dry- 
docks, caissons, sea coast defenses, etc.. 
is still another class of concrete con- 
struction where the Rex Pumpcrete has 
gained wide favor through its simplicity 
and easy adaptation to all types of job 
conditions. 






At right is shown a Rex Pumpcrete 
which is pumping concrete for a long 
jetty on the shore of Lake Michigan, 
with pipe line extending far out into the 
lake. This ability to transport concrete 
from mixing unit to distant form work is 
the Pumpcrete's and the Pumpcrete's 
alone. No other concrete placing meth- 
od offers this inherent advantage. If 
you bid this class of work, Pumpcrete is 
probably the cost-saving answer.

IF YOU RID UNUSUAL OR INACCESSIBLE I0BS 




Many concrete construction jobs offer 
problems that make them inaccessible 
by ordinary concrete placing methods. 
It is important to note that many jobs 
which ordinarily could only be placed 
at prohibitively high costs, become or- 
dinary, simple jobs when the Rex Pump- 
crete is brought into action. For in- 
stance, the Rex Pumpcretes have placed 
concrete in such difficult spots as tur- 
bine chamber linings and power house 
underp innings: Pumpcrete has placed 
the concrete for track elevations and 
tunnel linings without interfering with 
the flow of traffic. This last is shown in 
the picture at the left. Here the Rex 
Pumpcrete is pumping concrete for tun- 
nel lining without even the slightest in- 
terruption of regular railroad traffic. 
Before you bid complicated, inaccess- 
ible types of jobs, see how easy and 
profitable they can be when placed 
with the Rex Pumpcrete and pipe line. 



13 











WHAT IS THE REX PUMPCRETE? 

The Rex Pumpcrete is a pump that pumps concrete through a pipe line. It is a rugged 
horizontal piston pump with large size mechanically operated outlet and inlet valves. 
Concrete from a hopper above the valve chamber is drawn into the cylinder on a suction 
stroke and expelled into the pipe line on a pressure stroke. The pipe line is completely 
filled and there is a continual flow of concrete from the end of the line. 





HOW HIGH AND HOW FAR WILL 
IT PUMP CONCRETE? 

The distance concrete can be pumped is dependent on the diameter of the pipe, the 
number of elbows required in the line, and the elevation of discharge above the Pump- 
crete. Generally speaking, the Rex 160 Pumpcrete can pump concrete a horizontal dis- 
tance of 800 feet, or a vertical height of 100 feet. Larger Pumpcretes are capable of 
pumping as high as 120 feet or as far as 1200 feet — and even farther with plastic con- 
crete. Any combination of horizontal and vertical pumping within these limits can be 
handled very efficiently, thus enabling you to place concrete from one set-up to all 
points within its range. 





WHAT IS ITS CAPACITY? 

The Rex 160 Pumpcrete has a capacity of 15 to 20 cubic yards per hour — ideal for work- 
ing with 10-S or 14-S Mixers, Pavers or ready-mixed concrete delivery. Other sizes of 
Rex Pumpcretes have capacities up to 65 cubic yards per hour. Under normal set-up 
conditions and with good average concrete, the Rex 160 Pumpcrete will usually average 
better than 15 cubic yards per hour with the other sizes of Pumpcretes offering corre- 
spondingly higher averages. 





WILL IT HANDLE ALL MIXES? 

With a 6 inch pipe line, nearly all commonly used mixes can be pumped by the Rex 160 
Pumpcrete, provided they are of a workable consistency with a maximum aggregate size 
not larger than 2 inches. The larger Pumpcretes with larger diameter pipe lines are 
capable of pumping mixtures containing maximum aggregate sizes up to 3 inches. 
Practically all mixes ordinarily used on average concrete placement jobs can be easily 
and efficiently pumped by Rex Pumpcretes. 



14 











WHAT ABOUT OPERATING COSTS? 

The operating costs of the Rex Pumpcrete involve the cost of power (either gasoline or 
electric where available), the cost of lubrication and the cost of the operator. Ordinarily 
power, grease, and oil will rarely exceed 2c per cubic yard. It must be borne in mind that 
the cost of the operator depends upon the prevailing wage scale in your locality. 





WHAT ABOUT MAINTENANCE COSTS? 

Considering the fact that concrete is extremely abrasive, the maintenance cost of wear- 
ing parts of the Pumpcrete is surprisingly low. Easily replaceable wearing parts that 
come in contact with the concrete are made of special wear-resistant alloy steel. Wearing 
parts ordinarily have a working life of from 4,000 to 10,000 yards before replacement is 
necessary; and in pumping the first 3,000 to 5,000 yards, the maintenance cost per 
cubic yard of wearing parts is practically nothing. The maintenance cost of replace- 
ment parts per cubic yard is no more at 50,000 yards of life than at 10,000 yards of life. 





WHAT ABOUT PIPE HANDLING COSTS? 

Due to the quick-acting couplings on the pipe, the puddling crew, or others in the com- 
mon labor class, generally handle the pipe line, especially with the 160 Pumpcrete. 
Pipeline costs are difficult to segregate from the puddling costs. However, Pumpcrete 
owners have reported pipe handling costs from 2c per cubic yard on 24 inch slabs, to 
10c per cubic yard on 6 inch slabs and up to 12c per cubic yard on high, fairly thin 
walls. Accurate pipe handling costs can best be estimated after job requirements and 
distribution methods are known. 





WHAT'S YOUR QUESTION? 

A job like yours has been pumped by Pumpcrete! Whatever question you might have 
regarding the use of the Pumpcrete on any particular job, Rex can answer it. We have 
answered the same question for others in our experience of pumping millions of cubic 
yards of concrete on every conceivable type and size of job. Rex Pumpcretes have 
placed concrete on bridges, viaducts, buildings, housing projects, tunnels, overpasses, 
underpasses, filtration plants, reservoirs, locks and dams, culverts, warehouses, etc. This 
is a record of experience that guarantees the correct solution to your pumping problem.

On this United States Army Quartermas- 
ter's depot, two Rex 200 Double Pumpcretes 
pumped 52,000 cubic yards of concrete into 
the footings, columns, walls and floor 
slabs. It is a four-story building 200 ft. 
x 975 ft. in area. This is just another in- 
stance of the economical and practical 
application of placing concrete by the 
Pumpcrete method in building construction 




Here another ordnance building where Pump- 
crete is being used advantageously. Here 
again the Pumpcrete is economically placing 
concrete in the columns, walls and floor slab. 
The pipe line mounted on horses is easy to 
set eas tc take down and move If you
